How the SL182916-XL model number is decoded
envelope 80×110×19 mm with a 15.0 mm radial section; every available circumferential space carries a roller because there is no cage C is 94 kN and C0 126 kN; with a C/C0 ratio of 0.75 the 19 mm-wide full complement concentrates on extreme static and steady radial capacity rather than speed the fatigue load limit Cur is 21.7 kN, the limiting speed 3,500 r/min and the thermal reference speed 2,220 r/min — full-complement roller-to-roller contact keeps both speeds well below caged cylindrical bearings of the same size the dynamic rating is 1.18 kN per millimetre of the 80 mm bore and 4.95 kN per millimetre of the 19 mm width, figures that explain the use of this bearing in compact, heavily loaded gearbox positions mass is 550 g (0.26 g per mm² of the 110×19 mm envelope); the stiff, thick rings keep raceway deformation low under peak loads with a 80 mm bore this is a heavy-industrial bearing: 550 g of stiff ring and roller set, specified where rigidity matters more than speed The semi-locating function means this bearing locates the shaft in one axial direction and floats in the other — useful in two-bearing shafts where one position is fixed and the other absorbs expansion The -XL suffix is the Schaeffler X-life mark: interchangeable envelope with the basic bearing, but higher load capacity and lower running temperature at the 3,500 r/min limit. Typical applications include compact slow-speed agitator drives, planetary gear bearing positions and crane travelling-wheel mechanisms, where the 110 mm outside diameter and 94 kN dynamic rating match the duty. In compact slow-speed agitator drives the unit fits a compact 80 mm seat, and in planetary gear bearing positions the 550 g mass suits the compact, space-optimised housing. Designers also specify it for crane travelling-wheel mechanisms, relying on the 19 mm width and the published 126 kN static rating. Press-fit the correct ring: the rotating ring needs interference while the floating ring must slide on its seat to perform the non-locating function. Use the rib structure correctly: SL18/SL1850 give one-direction axial guidance, SL0149 locates both ways and SL0249 floats — pairing two locating bearings on one shaft binds thermal growth.
Typical equipment & failure modes
Common applications
- heavy industrial gearbox shafts
- construction machinery slewing drives
- vibrating and oscillating machinery
- rope drums and winch drums
Known failure patterns
- raceway pitting from overloaded slow-speed positions where the cageless rollers repeatedly stress one contact band
- rib and roller-end scoring when applied axial thrust exceeds the semi-locating capacity
- roller smearing from roller-to-roller sliding at speeds above the limiting value
- edge loading and premature spalling caused by undetected shaft/housing misalignment (full-complement rows cannot self-align)
- brinelling of the raceways from static shock during mounting or transport of the heavy rotor
- lubricant starvation in the tightly packed roller set, especially in the double-row executions
- freting and creep on a loose ring seat under a rotating load
- contamination wear in open gearbox positions with damaged seals or breathers
- false brinelling from micro-movement while the shaft is stationary under vibration
Selection pitfalls — read before you substitute
- Press-fit the correct ring: the rotating ring needs interference while the floating ring must slide on its seat to perform the non-locating function.
- Use the rib structure correctly: SL18/SL1850 give one-direction axial guidance, SL0149 locates both ways and SL0249 floats — pairing two locating bearings on one shaft binds thermal growth.
- C0 is the number that tempts overload in slow machinery, but fatigue life is still governed by the dynamic C rating and lubricant film.
Frequently asked questions
What are the dimensions of the SL182916-XL?
The SL182916-XL is a SL1829 single-row full-complement semi-locating cylindrical roller bearing with 110 mm outside diameter, 80 mm bore and 19 mm width, envelope 80×110×19 mm. Mass is 550 g.
What does the SL182916-XL designation mean in the FAG/INA HR1 catalogue?
SL182916-XL identifies this SL1829 single-row full-complement semi-locating cylindrical roller bearing in the Schaeffler HR1 rolling bearings catalogue; the -XL suffix marks the X-life execution. The envelope is 80×110×19 mm and the catalogue ratings are C 94 kN, C0 126 kN, Cur 21.7 kN.
What is the load capacity of the SL182916-XL?
The basic dynamic load rating C is 94 kN and the basic static load rating C0 is 126 kN; the fatigue load limit Cur is 21.7 kN.
What is the maximum speed of the SL182916-XL?
The limiting speed is 3,500 r/min and the thermal reference speed is 2,220 r/min. In the Schaeffler catalogue the reference speed is the thermally permissible running speed under defined load; the lower of the two values governs each application.
What is the locating function of the SL182916-XL?
This is a semi-locating bearing: one rib on the outer ring and two on the inner ring guide the shaft axially in one direction, while the other direction is free for thermal expansion.
